Go play the MarieTherese levels and hope for a box dying and her having fired her special… Weird.
I’ll have to look for that. If it happens again, post a screenshot. It sounds really funny.
Just saw this happen right before I saw your post. Happened on Epic Stage 7. I never record my fights, so I can’t show a screenshot or video, but I can confirm that it does happen, and I can confirm that you still get your challenge coin, which I was slightly worried about.
There are also some weird visual glitches with Marie Therese and those boxes. Empty stage without ending and an appearing zombie after a few turns where a box was.
